FIRST RECORD OF FRITILLARIA HELENAE IN THE MEDITERRANEAN SEA

In the last two decades multiple new gelatinous planktonic species were recorded in the Adriatic. Their arrival has been positively correlated with increasing sea temperature as well as with different circulation patterns in the Ionian Sea. The direction of the Ionian Sea Gyre causes advection of different water masses in the Adriatic. During its cyclonic phase it brings mainly warm and saline Eastern Mediterranean water, while during anticyclonic phase it brings more of Atlantic and Western Mediterranean waters. Here we present first record of Fritillaria helenae (Tunicata, Appendicularia) for the Mediterranaen Sea (Garić and Batistić, 2016). Fritillaria helenae was so far only known from the Atlantic. It was found in the South Adriatic in autumn 2014 when a marked drop in salinity was recorded, which suggests increased inflow of Atlantic/Western Mediterranean waters into the Adriatic.
